Dearborn MI deck permit rules — the basics

Deck construction in Dearborn requires a building permit applied for via the BS&A portal at dearborn.gov/resources/forms-documents/permit-applications, or by mail to Economic Development Department, ATTN: Permits, 16901 Michigan Ave., Ste. 7, Dearborn, MI 48126. The permit application requires site plan, framing plan, footing detail, and guardrail specifications. After approval, the permit must be picked up in person at the Dearborn Administrative Center by the homeowner, contractor, or authorized representative. Michigan LARA-licensed contractors must also be registered with the City of Dearborn before pulling permits. Contact 311 or DBNinspections@dearborn.gov with questions.

Wayne County, Michigan has a frost depth of approximately 42 inches — one of the deepest requirements of any city in this series. All deck footings must extend to undisturbed soil at this depth to prevent frost heave. Call Michigan 811 (miss dig, 811 or missdiggy2k.com) at least 3 business days before any footing excavation to locate underground utilities — DTE Energy electric and gas lines are in many Dearborn residential neighborhoods at various depths. The footing inspection before concrete placement is the first required milestone after permit issuance.

Michigan's Residential Code (based on the IRC) requires 36-inch minimum guardrail height on open sides of decks 30 or more inches above adjacent grade — 6 inches shorter than California's 42-inch standard. Pre-1978 housing in Dearborn means EPA RRP procedures apply for any deck ledger attachment that disturbs lead-painted exterior siding or trim. Verify contractor EPA RRP certification for any deck project that involves drilling or nailing through painted exterior surfaces of a pre-1978 Dearborn home.

Dearborn MI home improvement: practical guidance for homeowners and contractors

Dearborn's permit process has one distinctive step that surprises many applicants: building permits must be picked up in person at the Dearborn Administrative Center (16901 Michigan Ave.) by the homeowner, contractor, or a representative with a notarized letter of authorization. You cannot simply download or email your permit — even after online approval. Build this in-person pickup step into your project timeline. Trade permits (electrical, plumbing, HVAC) have more flexible mail-in options. For permit questions, call 311 or email DBNinspections@dearborn.gov.

Michigan's dual contractor licensing system — LARA state license plus Dearborn city registration — means two separate credential verification steps. Check the contractor's Michigan LARA license at michigan.gov/lara, and confirm their City of Dearborn registration status by calling the City Clerk's Office at (313) 943-2015. Both must be current. Michigan Residential Builders (RB) and Residential Maintenance & Alteration Contractors (RMA) have different scopes — an RMA license covers repairs and alterations to existing residential structures, while an RB license is needed for new construction and additions. Verify that the contractor's specific license classification covers your project type.

DTE Energy provides both electricity and natural gas to Dearborn — a single utility company serving both energy needs. For electrical service upgrades or gas service modifications, contact DTE Energy at dteenergy.com or 1-800-477-4747. DTE Energy's residential service scheduling typically runs 2–4 weeks for service entrance work; coordinate DTE and the city permit in parallel. DTE Energy also offers rebates for energy efficiency improvements including insulation, high-efficiency HVAC, and energy-efficient appliances — check dteenergy.com for current rebate programs before finalizing any HVAC or insulation project in Dearborn.

Dearborn's housing stock — primarily 1920s through 1950s construction with a smaller share from the 1960s–1970s — means virtually every residential property in the city predates 1978. EPA RRP lead paint procedures are the standard, not the exception, for Dearborn renovation work. Asbestos-containing materials (floor tiles, pipe insulation, ceiling textures, drywall joint compound) are also common in pre-1980 Dearborn homes. Contractors performing renovation work must hold EPA RRP certification for lead paint work. Asbestos testing before disturbing suspect materials is a best practice in Dearborn's older housing stock. These requirements apply regardless of whether the work requires a permit.

Dearborn MI permit context: Michigan LARA licensing, DTE Energy, and Motor City heritage

Dearborn is Wayne County's second-largest city, home to approximately 110,000 residents and deeply tied to Ford Motor Company — Henry Ford was born in Dearborn, and Ford's world headquarters and the iconic Ford River Rouge Complex are both located here. The city has the largest Arab American community per capita in the United States, and its dense residential neighborhoods were developed primarily in the 1920s through 1950s around the automotive industry's growth. This means the vast majority of Dearborn's housing stock predates 1978, making EPA RRP lead paint and potentially asbestos-containing materials relevant to virtually every renovation project in the city. Dearborn's winters are genuine Michigan winters — deep frost, ice, snow — and the city's building code reflects this fully.

Dearborn's permits are handled by the Economic Development Department at 16901 Michigan Ave., Suite 7, with a plan review process that typically takes 5–10 business days. Building permits must be picked up in person at the Dearborn Administrative Center by the homeowner, contractor, or a designated representative with a notarized letter of authorization. BS&A online portal handles permit applications and inspection scheduling for electrical, plumbing, and HVAC permits. Contact 311 (city services) or email DBNinspections@dearborn.gov for permit questions. The Electrical Division is at 313-943-2414 and the general response center at 313-943-2150.

Michigan contractor licensing is administered by LARA (Department of Licensing and Regulatory Affairs) Bureau of Construction Codes. Michigan requires: Residential Builders (RB) and Residential Maintenance & Alteration Contractors (RMA) for general residential work; Michigan master electrician license plus contractor registration for electrical work; Michigan plumbing license; Michigan mechanical license. Verify any contractor's active Michigan LARA license at michigan.gov/lara. Contractors must ALSO register with the City of Dearborn — contact the City Clerk's Office at (313) 943-2015 for registration information. Both the state LARA license and the Dearborn registration must be current before permits can be issued.

DTE Energy provides both electricity (Detroit Edison) and natural gas (MichCon/DTE Gas) to Dearborn — a single utility company for both services, contact at dteenergy.com or 1-800-477-4747. For service entrance changes, panel upgrades, or gas service modifications, coordinate with DTE Energy. Michigan's net energy metering law allows residential solar customers to earn retail-rate credits for solar exports to the grid for systems sized up to 150% of annual consumption. Wayne County's frost depth is approximately 42 inches — one of the deepest in this series — requiring footings to extend well below grade for all structural projects. Michigan's residential code requires ice and water shield at roof eaves due to genuine ice dam conditions in Wayne County winters.

Common questions about Dearborn MI deck permits

What is the frost depth for deck footings in Dearborn MI?

Approximately 42 inches to undisturbed native soil for Wayne County, Michigan (Climate Zone 5). This is one of the deepest frost depth requirements of any city in this series. All deck footings must extend to at least this depth. The building inspector must approve footings before any concrete is poured. Call Michigan 811 (or missdiggy2k.com) at least 3 business days before any footing excavation.

What is the guardrail height for decks in Dearborn MI?

Michigan's Residential Code (based on the IRC) requires a minimum 36-inch guardrail height on open sides of decks 30 or more inches above adjacent grade. This is 6 inches shorter than California's 42-inch standard. The 36-inch minimum must include 4-inch maximum sphere openings between balusters and a graspable handrail on stairs with 4 or more risers.

Dearborn MI home improvement: the Motor City legacy and what it means for permits

Dearborn's identity is inseparable from the Ford Motor Company — Henry Ford's birthplace, Ford World Headquarters, and the River Rouge Complex all anchor this community. The auto industry drove Dearborn's residential development in the 1920s through 1950s, creating the dense, working-class neighborhoods of bungalows, Cape Cods, and Colonial Revival homes that still define the city's housing stock. This heritage means two things for home improvement projects: first, virtually every Dearborn home predates 1978, making EPA RRP and asbestos awareness standard rather than exceptional; second, Dearborn's contractor market is deep and experienced, with many Michigan LARA-licensed contractors who understand the specific challenges of the city's older housing stock.

The City of Dearborn has been modernizing its permit process through the BS&A online portal at dearborn.gov/resources/forms-documents/permit-applications, which handles application submission, fee payment, and inspection scheduling for most permit types. However, one distinctively in-person step remains: building permits must be picked up in person at the Dearborn Administrative Center (16901 Michigan Ave., Suite 7) after approval. Contractors and homeowners should factor this into project timelines — plan review typically takes 5–10 business days, followed by the in-person pickup. For trade permits (electrical, plumbing, HVAC), mail-in applications to the same address are accepted, making these more flexible than building permits. Note: The city periodically upgrades its software systems; contact 311 or DBNinspections@dearborn.gov to confirm current portal availability and requirements.

Michigan's contractor licensing through LARA (Department of Licensing and Regulatory Affairs, Bureau of Construction Codes) creates specific license types that differ from California's CSLB and New Mexico's CID systems. Key Michigan licenses for residential work: Michigan Residential Builder (RB) — required for new construction and additions to residential buildings; Michigan Residential Maintenance & Alteration Contractor (RMA) — for repairs, renovations, and alterations to existing residential structures. Both RB and RMA are issued by LARA's BCC (Bureau of Construction Codes). Trade licenses — electrical master, journeyman, plumbing, and mechanical — are issued separately and their holders must be the qualifying agent behind a registered contracting business. Verify the license type and active status of any Dearborn contractor at michigan.gov/lara before signing a contract. The contractor must also be registered with the City of Dearborn — confirm via City Clerk at (313) 943-2015.

Dearborn's Arab American community — the largest per capita of any US city — has been a central part of the city's identity for decades, and is increasingly influential in the city's home improvement and construction market. Mayor Abdullah Hammoud, the first Arab American mayor of Dearborn, has focused city government on housing quality, flood preparedness, and neighborhood investment. Dearborn has experienced recurring flooding issues from combined sewer overflows during heavy rain events — a factor relevant to basement renovation, sump pump installation, and backwater valve requirements. The city's flood preparedness resources at dearborn.gov/residents/flood-preparedness can help homeowners understand basement waterproofing permit requirements and flood mitigation options that may also be relevant for home improvement projects.
